Hey TB, I have a Fusion 550 and the Master volume crackles like mad whenever I touch it to turn up or down, I mean really bad static and popping to the point where if I'm not careful, it sounds like I may possibly blow my speaker out. (All the other controls are perfectly fine). My master volume (for the most part) never goes past the 9 o'clock position); but whenever I touch it ever so slightly, that happens. That, and everytime I first turn it on, after 5 minutes or so the volume (all on it's own) just goes down say like 1/4 or 1/3, then after say about 3-5 minutes it'll come back to normal volume (very weird); but other than that, it's perfectly fine until whenever I shut it down/off. Anyone ever heard/experience anything like that before? Initially I thought it just may need a little tuner cleaner (I haven't tried it yet), but I think it's a little more serious than that because of the weird losing volume thing that happens. 'Sound familiar to anyone? Thanks in advance.
